"Switch User" Language problem

Question

Hi Everybody,

I have a problem with the UI language with Windows and I do not have any idea how to solve it.

I have a Windows 11 Enterprise version 10.0.22631 with italian switzerland (it-CH) as main language, as you can see from the image below:

When I want to switch the user account, I can see correctly the italian button "Disconnetti", which means "Log off", but the button "switch user" is in english:

Do you have any idea on how I can translate the "Switch user" button into italian?

Here some informations:

PS C:\Windows\system32> dism /online /get-intl

Deployment Image Servicing and Management tool

Version: 10.0.22621.2792

Image Version: 10.0.22631.4460

Reporting online international settings.

System locale : it-CH

The operation completed successfully.

If I try to do Set-WinUILanguageOverride it-IT and after a reboot, the dism output do not change.

In the regedit, key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MUI\UILanguages I have all keys, here the en-US and the it-IT:

Thank you for any help.

Best regards

Edit:

I don't know if maybe I can change a .mui file to change the "switch user" in Italian, but I don't know where I can search

1. Ensure Italian Language Pack is Fully Installed

• Go to Settings → Time & Language → Language & Region.
• Check if Italian (Italy) is fully installed.
• If not:
  • Click Add a language → Search for Italian (Italy) → Install it.
  • Make sure to include Language Pack, Basic Typing, Handwriting, and Speech.

1. Set Italian as the System UI Language

• Open Command Prompt (Admin) or Windows PowerShell (Admin).
• Run the following commands:

    dism /online /set-allintl:it-IT  
    dism /online /set-syslocale:it-IT  
    dism /online /set-inputlocale:it-IT  
    dism /online /set-uilang:it-IT
  

• Reboot your system.

1. Use Set-WinUILanguageOverride

• Open PowerShell (Admin).
• Run:

    Set-WinUILanguageOverride -Language it-IT
  

• Reboot your system.
• Verify with:

    Get-WinUILanguageOverride
  

1. Force Italian in the Registry

• Open Regedit as an Administrator.
• Navigate to:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MUI\UILanguages
• Delete the en-US key (backup first).
• Reboot your system.

1. Verify Results

• After rebooting, run:

    dism /online /get-intl
  

• Ensure it-IT is the default system UI language.
• Check if Switch User and other UI elements display in Italian.

Hi Ziad,

I've tried to do what you wrote but the problem is the same, and some computers the dism commands do not works because the image is offline (as the dism says)
